Lathe - tool offset in Y does not work

Hello,
I have a CNC mill. For a small project, I would like to use it as a lathe. Therefore created a new configuration, set LATHE=TRUE in the AXIS section of the ini file. My setup is as follows:
- the Z & X-axes are preserved,
- the workpiece is mounted in the spindle,
- there are 3 lathe tools mounted on the mill table in different Y distances - by moving the Y-axis I would like to change tools.

Then I set up 3 tools in my tool table - with various X, Y a Z offsets. In the program, I expect that issuing tool change followed by G43 causes the machine to apply these offsets in the next machine move. It works well for X and Z, but Y-axis seems to be ignored by the system. However, when I open the DRO tab in AXIS, I can see Y TLO applied. But the physical movement does not correspond with the Y offset - the machine does not move in the Y direction. The Y-axis works I can jog with no problems. It is also shown on DRO screen. Just the Y-axis offset is not applied.

What have I misconfigured? How can I fix it?

Please post your config files. and what version of linuxcnc are you using?

Lathes use only X and Z axis, so to use Y axis for changing tools my gues is it would have to be set as a toolchanger by using M codes or remap. Chris is much more experienced for that, so i will shut up now.

Thank you guys for a quick response. I attach my configuration. Just for illustration for what my setup looks like I a video from a first test of the setup (using only a single tool): photos.app.goo.gl/3KPXwsMZFytU6hhZ9

Very nice, thank you.

I don't think you miss configured.
I think that the programmers of AXIS assumed lathes don't ever have a Y axis.

In fact i am wondering how you homed the Y axis?
